Abstract
The invention relates to an electric mower with a filter screen blocking prompt function. The electric mower comprises a case with an opening formed in the bottom, blades arranged at the opening of the case, a motor arranged in the case and driving the blades, and a collecting box arranged in the case. A pipeline leading to the collecting box is arranged above the blades and provided with an impeller driven by the motor. An opening leading to the outside of the case is formed in the side face of the collecting box. A filter screen covers the opening. A handle used for pushing the mower and wheels are arranged outside the case. A flow meter is arranged behind the filter screen. The output end of the flow meter is connected with an indicator lamp. A battery for supplying power to the motor is arranged in the case. A port used for charging the battery is formed in the case. According to the electric mower with the filter screen blocking prompt function, as the flow meter is arranged behind the filter screen, when the filter screen is blocked, air flow is reduced, then the indicator lamp is controlled to prompt blocking, the overall structure is simple, and cost is low.
Description
Technical field
The present invention relates to a kind of power-operated mower, particularly relate to a kind of power-operated mower with filter net jam prompt facility.
Background technology
Existing mower only has mowing function mostly, and after being rested and reorganized on lawn, also need to collect after cutting broken grass blowout lawn with hair-dryer, efficiency is lower.
Small part mower then has collecting function, utilizes negtive pressure forced air to flow, is then collected by weeds.And air flow passage must install screen pack in its exit.After screen pack blocking, namely air flow amount significantly reduces, and namely its collecting function cannot realize.
Generally, this screen pack needs people's manual removal and then observes its stopping state, cannot accomplish real-time monitoring.
Summary of the invention
The present invention wants technical solution problem to be: the shortcoming overcoming above-mentioned technology, provides a kind of power-operated mower with filter net jam prompt facility.
In order to solve the problems of the technologies described above, the technical scheme that the present invention proposes is: a kind of power-operated mower with filter net jam prompt facility, comprises the housing of bottom opening, is arranged at the blade at described shell nozzle place, is arranged in described housing and the collecting box driving the electromotor of described blade and be arranged in described housing; The top of described blade has the pipeline leading to described collecting box; Described pipeline has an impeller by described motor driven; The side of described collecting box has the opening led to outside housing; Described opening is coated with screen pack; There is outside described housing the handle for promoting mower and wheel; Described screen pack rear has a flowmeter; The output of described flowmeter is connected with indicator lamp; Also there is in described housing the battery for described motor; Described housing also has the interface for described battery charging.
Such scheme further improves and is: the below of described blade has wire netting.
Such scheme further improves and is: the front end of described housing bottom has rigidity comb.
The power-operated mower with filter net jam prompt facility provided by the invention, arranges flowmeter at screen pack rear, has served as filter net jam, and air mass flow reduces, and namely control indicator lamp prompting blocking, overall structure is very simple, with low cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention's preferred embodiment.
Embodiment
Embodiment
The power-operated mower of what the present embodiment provided have filter net jam prompt facility, as shown in Figure 1, comprise bottom have opening housing 1, be arranged at housing 1 opening part blade 2, be arranged in housing 1 for the collecting box 4 driving the electromotor 3 of blade 2 and be arranged in housing 1; The top of blade 2 has the pipeline 5 leading to collecting box; Pipeline 5 has an impeller driven by electromotor 36; The side of collecting box 4 has the opening led to outside housing 1; Opening is coated with screen pack 7; There is outside housing 1 handle 8 for promoting mower and wheel 9; The rear of screen pack 7 has a flowmeter 11, and the output of flowmeter 11 connects indicator lamp 12; Also there is in housing 1 the battery (not shown) for electromotor 3 power supply; Housing 1 also has the interface (not shown) of battery charging.Flowmeter 11 and indicator lamp 12 are also by this powered battery.
The below of blade 2 has wire netting, to increase safety, avoids occurring accidentally injuring, can also guarantee that bulk stone damages blade 2 simultaneously.
Further the bottom front of housing 1 has rigidity comb 10, in order to clear away stone or other hard object in front, avoids damaging blade 2.
During work, electromotor 3 is with operate at constant speed, promote blade 2 and impeller 6, blade 2 pairs of lawns are cut, and 6, impeller produces negative pressure, air is entered by the bottom opening of housing 1, through piping 5, finally discharged by screen pack 7, like this, air draught by the careless intake line 5 of chopping, then can drop into collecting box 4.The invariablenes turning speed of electromotor 3, so the rotating speed of impeller 6 is also constant, so the air mass flow substantially constant in pipeline.When screen pack 7 blocks time, its exhaust efficiency reduces, and when air mass flow is reduced to a half of normal value, namely the indicator lamp 12 be connected with flowmeter 11 lights, and teaching process personnel need check cleaning filter net 7.
In order to prevent erroneous judgement, the flow that flowmeter 11 detects is reduced to the half of normal value and continues more than 10 seconds, just then indicator lamp 12 lights.
The present invention is not limited to the concrete technical scheme described in above-described embodiment, and in addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacing and being formed, and are the protection domain of application claims.
